My invention relates to improvements in Machines for making paper bottles and particularly in reference to a swaging mechanism used in a machine forming the subject matter of an apl plication bearing date the 9th day of February 1933,'and filed under Serial No. 656,014, and the object of the present invention is to provide a means whereby the tapered upper end of the paper bottle may be swaged so as to produce longitudinal corrugations to increase its strength andvutility.

The invention consists of a crimping or corrugating mechanism having the interior thereof 'shaped to correspond to the contour of the bottle, such mechanism comprising corrugating segments and held in a suitable housing and being longitudinally operable in relation to the mandrel upon which the bottle is held, and the parts whereby it is given its movement being arranged and constructed in detail as hereinafter more particularly explained.

The housings 6 and 7 have located at one end the sleeve 9 provided with a projection 10 which extends through a slot 11in the cylindrical end 12. The cylindrical end 12 is provided with an inclined rib 13 for a purpose which will hereinto after appear. 14 is a cam provided with a cam groove 15 and is located in a recess in the bed plate and provided with a cover 16.

17 is a rod which is provided with a cam follower 19 which extends into the groove 15 of the cam 14. The cam follower 19 is secured to the rod 17 at one end and the other end is threaded and extends into a threaded orifice 20 in the end 12, being adjustably held therein by a nut 21.

22 are the corrugating segments which are tapered at one end 23 in the interior, the opposite end 24 being interiorly cylindrical.

The general contour of the corrugating mechanism is cone frustum shape so as to fit within the cone frustum shaped interior of the housings 6 or '7. The corrugating segments 22 make up a complete corrugating mechanism and have secured to them the outer T shaped members 25 by a screw 26. The T shaped members 25 are provided with lateral extensions 27. The lateral extensions 27, of the T shaped members 26 are slidably held in the grooves 28 of the inverted T shaped members 29 which are rigidly'secured to the interior of the housings 6 and 7.

In the housing 6 is located the crimping or corrugating mechanism comprising several segments as hereinbefore referred to, and at the tapered end of each segment is located the rib 30, (see Figs. 4 and 9). The number of ribs as well as the ends of the segments shown in Fig. 4 are represented as less in number in proportion to those that are really used for the. sake of clearness.

\ At the opposite end of the corrugating segments is locatedfa circular plate 32 against the flange 31 of which the corrugating segments abut. The plate 32 has also an annular recess 33. The 'end 12 has a longitudinal extension 12 which projects mostly through the sleeve 9. 34 is a spiral spring which surrounds the projection 12 extending between the inner end of the cylinder 12 to and into the recess 33 in the plate 32.

35 is a'centralizer secured in the end of the projection or extension 12 and extending through the plate 32 as indicated. The centralizer 35 is provided with an enlarged end 36 tapered at the outer end as indicated. This centralizer is designed to ensure the centralization of the mandrel when the corrugating mechanism encirclesthe mandrel 38, the mandrel being recessed at 37 as indicated in Figs. 5 and 6. It will be understood that the mandrel is stationary as to longitudinal movement. 39 is a collar which extends over the mandrel and the inner end thereof for the purpose which will hereinafter appear.

40 is a bracket secured to the portion of the frame and 41 is a rod pivoted on a pin 42 in the bracket 40 and carrying at its opposite end a roller 43 for a purpose which will hereinafter appear.

In Fig. 3, I show the crimping or corrugating mechanism of the housing 7 comprised of corrugating segments, the tapered inner periphery being smooth, the object being so that when the corrugating segment is carried on to the mandrel it will only slightly crush the paper over the grooves 44 formed in the tapered end 45 of the mandrel. This crushing of the paper along the edge of the grooves formed on the tapered end of the mandrel is scarcely perceptible but is sufiicient to give a start to the actual forming of the grooves when the bottle is brought on the mandrel to the next crimping or corrugation mechanism provided with the impression ribs 30 contained in the housing 6 (see Fig. 4).

It will of coure be understood, therefore, that as indicated in Fig. 1, there are two crimping or corrugating mechanisms, the primary crimping or corrugating mechanism (see Fig. 3) and the final crimping or corrugating mechanism (see Fig. 4), which are necessary to effectually corrugate the tapered neck. The movement of each crimping or corrugating mechanism is the same, and I shall now describe such movement.

A longitudinal movement is imparted to the corrugating mechanism through the medium of the cam 14, cam follower 19 and connecting rod 17, the housings 6 and 7 sliding freely through the guideways 3. With reference to Fig. 4 it will be seen that the longitudinal movement of the corrugating segments 22 will be arrested when they come in contact with the collar 39 of the mandrel 38. With the corrugating segments 22 thus halted the housing continues its longitudinal movement. Hence the corrugating segments 22 will be forced downwardly in a radial direction in the slideways 28 until the ribs. 30 shall enterthe grooves 44, thus forcing the paper to attain the desired corrugated effect. A

When the housing first moves forward as indicated in Fig. 4, the roller 43 of the rod 41 rests near-the forward end of the housing. When the housing reaches the limit of its movement the roller 43 rests on the cylindrical end 12, the end of the rod 41 closely abutting the projection 10 on the sleeve 9, (see Fig. 5), and thereby holds the crimping or corrugating mechanism stationary from longitudinal movement through the medium of the sleeve 9 and plate 31 abutting the ends of the corrugating segments 22.

Upon the beginning of the backward movement caused by the cam and rod 17 the roller 43 rides up on the inclined way 13, the housing having previously moved so as to allow of the corrugating segments moving out radially so as to permit their withdrawal freely from the large end of the mandrel 38. This movement is continued until the rod is out of engagement with the lug 10 whereupon the spring 34 will restore the corrugating segments into their normal position in the housing as indicated in Fig. 4.

From this description it will be seen that I have provided a very effectual mechanism whereby the tapered end of the bottle may be swaged mandrel and comprising a series of sections radially arranged, a socket frame carrying the former sections, means for imparting a longitudinal movement of the socket frame, and. a collar on the inner end of the mandrel with which the end of the sections of the former are designed to contact to force them inwardly when the socket frame has reached the limit of its longitudinal movement.
